Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480694, here are decompositions:
- 13 + 31480681 = 31480694
- 73 + 31480621 = 31480694
- 313 + 31480381 = 31480694
- 577 + 31480117 = 31480694
- 673 + 31480021 = 31480694
- 733 + 31479961 = 31480694
- 877 + 31479817 = 31480694
- 937 + 31479757 = 31480694
Showing the first eight; more decompositions exist.
